The LGH-3004 FTIR continuous flue gas emission monitoring system is a premium optical analysis platform built around our self-developed dual swing corner-mirror interferometer. It leverages molecular "fingerprint" infrared absorption features, combined with Michelson interferometry and Fast Fourier Transform (FFT) algorithms, to achieve full-spectrum scanning of complex mixed gas matrices.
Designed for harsh operating conditions including waste incineration, hazardous waste treatment and petrochemical production lines, the system enables simultaneous quantitative analysis of SO₂, NOₓ, CO, polar pollutants (HCl, HF, NH₃) and greenhouse gases. It delivers state-of-the-art performance for multi-component, high-humidity, high-interference industrial flue gas monitoring.
· Excellent Vibration Resistance & High Stability
Proprietary electromagnetic dual swing corner-mirror interferometer with zero mechanical wear, immune to industrial on-site vibration.
· Ultra-high Sensitivity & Spectral Resolution
0.5 cm-1 spectral resolution, SNR > 52099:1; supports ppb-level detection under high-humidity conditions.
· Full-process High-Temperature Wet Measurement
Sampling and analysis operate at constant 180–250 °C to avoid condensation loss of soluble gases (HCl, NH₃) and deliver authentic accurate readings.
· Smart Regulatory Compliance Design
Fully compliant with HJ 212-2025; integrated anti-tampering verification, real-name logging and remote monitoring to lower O&M costs.
· High-temperature Sampling Unit
High-power heating probe matched with 180 °C heat-traced tubing to preserve original flue gas composition.
· FTIR Analysis Module
Core optical engine equipped with ZnSe beam splitter, 10 m long-path gas cell and liquid-nitrogen-free TEC-cooled detector.
· Preprocessing Control Unit
High-precision sampling pump, pressure regulator and automatic blowback system for long-term unobstructed gas circuit.
· Intelligent Analysis System
Adopts nonlinear least-squares algorithm with built-in library of 500+ gas spectra to automatically suppress water vapor interference.
